AUTO SIGNALING DEVICE.

Application fled mm, 14;, 1915. Serial Io. 211,275.

in in the art to which it appertains to make and use the same, referencebeing had to the accompanyin drawings, and to figures of reference mared thereon, which orm part of this specification.

' Like figures of reference refer to like parts.

This invention relates to auto signaling devices, particularly thoseused on rear of a ve icle to indicate the direction in which theoperator-is about to-turn.

One of the objects of this invention'is to provide a simply constructeddevice for carrying the signaling lamps and adapted to e mounted uponthe rear of a vehicle.

Another object is to provide two sets of lamps, one set for signali a riht or a left turn and the other set to s ow t e usual red rear signal ortail light, and to illuminate the number plate an A further object is toprovide was...

circuit, with lam s and switches for manually controlling e si ale andthe illumination of the. number p ate.

A further object is to provide a simple '6 sup rt for the lamps thatwill remain attaclird to the rear of the auto while the casing, whichcovers them is removed for repair or renewal of the lamps.

And a further object is to provide a rain to shield for the number latewhich will at the same time act as a re actor of light in illuminatingthe said plate.

With these and other objects my invention consists in certainconstruction, one embodimentof which is illustrated in the draw- I ingsand is hereinafter described its operation is explained and what I claim18 set forth. v

In the drawings,

1 is a'perspective view of a device embodying my invention, and adaptedto be mounted upon the rear of a vehicle. 1

D Figure 2 is a. perspective view of the rear wall of my device showingpartitioning walls i separating the signals.

Figure 3 is a vertical mid-sectional view, taken at right angles to theface of the device. This fi re also shows the wiring-in connection withthe lamps and switches.

Fi re 4 is a horizontal section taken on the line X-X of Figure 3. V

' In the figures, the device is shown made up of the following parts,from a back plate 1, integrally projects a, series of partition walls,respectively numbered 2, 3, 4 and 5.

and two wing walls, respectively numbered 6 and 7. On the rear of theplate 1, and depending therefrom, are two number plate lugs 8 and 9..There are also four other lugs, numbered respectively 10, 11, 12 and 13,having threaded holes A, A, A, A, for the reception of screws, whenattaching the outer casing. External to the plate 1 is another lug 14,adapted for the reception of'a bracket arm attac ed to a vehicle, notshown, afragment of which arm is numbered 15, shown in Figure 3, andheld on b the screw 16. Positioned in the plate 1 an surrounded bpartition walls 2, 3, 4 and 5, is a hole 17, or the passa of lamp wires.Fixed in each of the wal s 2, 3, 4 and 5 is an electric lamp. Theselamps are lettered B, C, D and E.

Adapted for attachment to the plate 1, is the outershell 18, having aflange 19 and projecting lugs 20, 21, 22 and 23, positioned to comeopposite the respective lugs 10, 12, 13 and 11. In the face 24 of theshell 18,

I is a round aperture 25 covered on the inside with a. red glass 26.Other recesses cut in the she of letters-L and R, and backed b a gassupported on the inside of the siiell 18, are shown in Figure 1. In thebottomof the shell 18 is a recess 27. A similar recess, registeringtherewith is made in the beveled reflector plate 28, which late isattached by screws 29, 29 to the she I 18. Depending from the lugs 8 and9 is the number plate 30.

Referring particularly to Figure 3, there are shown switches 31 and 32,and a battery 34, all of which are in circuit with the set of lamps, B,C, D and E. ,This circuit mag be described as follows: Lamps B and areconnected with the single switch 31, in'

the following manner, starting at the pole 35, a wire 36 passes on andbranches at the point 37 into two wires 38 and 39. The wire 38 a nnect'swith thelamp B, and the wire 39 connects with the lamp D. Returnnate therear tail illuminate the letter-J4. Si

ing from the lamp B, is the wire 40, which connects with the return wire41, coming from the lam D, merging with the wire 42 and connected withthe battery 34. Leadin from the battery 34, is the wire 43, Wllll'branches at 44 to a wire 45 connected with the switch 31, and to thewire 46, connected with the switch 32. The switch 32 has two poles 47and 48. From the pole 47 leads a wire 49, which connects with the lampE. The return wire. 50. connected with the lamp connects at 51 with thewire 52, which is conrtected at 53 with the wire 54, which in turn isconnected at the point 55 with the battery wire -12, and by means of thewires 43 and 46 and the leaf 56, the circuit throu h the lamp E and thepole 47 is completer. For the circuit on the lamp C, let us start at thswiQch-polcfi and passing in succession thi 'ihtgh the wire 57, the lamp(1, the return wire 5Sfthe point 51, the wire 52, the point 53, the wire54; the point 55. the wire 42, the battery 34. the wire 43, the wire 46.back to the s\vit"h 3il In operation, let us assume that the bracket arm15 is that of one attached to the rear of an automobile, and supportingthe device on the lug 14 and .the set screw 16. Also assume that thecircuit of wires is diagrammatic of wires leading from two switchespositioned within handy reach of the chauffeur in the front of theautomobile. These switches being numbered 31 and 32. Suppose that thechautl'eur desires to ilhimidanger signal having a red glass 26 and atthe same time desires to illuminate the number plate 30, he closes theswitch 31, which, by the circuit just (lescribed throws his batterycurrent upon the lamps B and D. Now assume that he desires to give toanyone following his automobile. a warning that he is about to turn tothe left, he will throw the switch 32 to close the circuit on, the pole47 and thus will nifying, in advance, the chaufi'eurs intention to go tothe left. If. on the contrary, he decides to go i to the right. hethrows the leaf 56 over in contact with the pole 48, and closes thecircult on the lamp C, in the rear of the letter R,- at the same timecuttin as the circuit on the lamp 1). The letter ll thus becomesilluminated, signifying the chaufl'eurs intention to go to the right.

In 'providin a reflector shield 28, in the shape that I o, I am alsoproviding a rain shield to the number plate 30. The under side of theshield 28 IS perferably painted white or per ared in some way to reflectlight. This evice is simple in its construction and cheap to make and isshaped to be ornamental as an attachment to the rear of the rehicle. Thelamps are easily reached for repair or renewal by removing the screws,from the lugs 10, 11, 12 and 13, to release the plate 1, upon which thelamps are supported, while the plate 1 remains secured to the bracket15.

Hari'ng-deseribed my invention, I claim,

As an article of manufacture, an auto signaling box adapted for thereception of lamps, comprising a shell having a flat face with aperturesforming signal characters, two opposite side faces, a bottom aperturedface, for the reception of a lamp, and a top curved face, a platefitting the open side of said shell," with means for attaching saidplate tosaid shell, said plate having integral therewith, in its centralortion, a square box having vertical and orizontal sides. the twovertical sides extending below the lower of the horizontal side, twoinclined walls projectin divergently from the upper corners of anti uarebox, the sides of said box and the sai inclined walls dividing saidshell into lamp compartments, a reflector hood mounted upon the underside 'of said shell, and means for attachin a name or number plate tothe rear of sai hood, upon said first mentioned plate.
